(Cl. 'I0-38) 3 Claims.

My invention relates to locks and refers more particularly to tumblerlocks or locks utilizing a `multiple of locking pins.

One object of myinvention is to provide a lock that has a plurality oflocking pins that are placed in the locking position by means of a keyso that when the key is withdrawn from the lock these pins are placed inthe locking position and when the key is placed in the lock the pins areout of locking position.

Another object `of my invention is to provide a lock that is operated bya sliding key that does not have to be turned at any time which key hasa substantially centrally located jagged slot.

A further object of my invention is to provide a lock that has amultiple of locking pins that can be set into thousands of combinationsby changing the coniiguration of the key slot and making the pins thatmove the locking pins to` suit the conguration of the key.

I attain these results preferably by the means illustratedin theaccompanying drawing, illustrating one application of the lock only,wherein like parts are referred to by similar numerals throughout theseveral views, in which:

Figure 1 is a plan of the lock showing the locking pins in thepath ofthe movable body.

Figure 2 is a plan of the lock showing the locking pins out of the pathof the mvoable body.

Figure 3 is an'end elevation of Figure 1, taken broken away of the takenon lines 8-3 of The lock is comprised of a body I carrying a fixedcylinder 2 that is provided with a keyway 3 adapted to slidably engagewith a flat key 4.

This cylinder 2 has two grooves 5 and 6`that match with the two holes 'Iand 8 adapted to slidably carry the legs 9 and I0 of the U shapedslidably movable element II, the leg 9 provided with three holes I2, I3,and I4 and the leg III with four holes I5, I6, I1 and I8 and a latch I9with a spring 20 and this latchenters into a groove 2|, to prevent theelement II from leaving the body I. l i t taken on lines 5-5 of Thecylinder 2 is preferably held within the body I by means of two pins 22and 23, which lock into the groove 24, the pin 22 also serving to holdthe plate 25, which forms the upper part of the keyway 3.

Directly below this keyway 3 are four holes 26, 2l, 28 and 29, whichcarry the slidable locking pins 3B, 3|, 32 and 33, each having a pin 34,35, 36 and 3l that project through theslots 38, `3l), 4l) and 4I, intothe keyway 3 in the path of the key 4, which key has a slot 42, so thatwhen the key is in the opening position, as shown in Figure 2, this keywill line up the pins, as shown in Figure 2 forcing them out of the pathof the slidv ing element II and when the key is Withdrawn, all of thelocking pins will be forced into the path of the movable element II, asclearly shown in Figure 1.

It is obvious that thousands of combinations could be made with thistype of lock whichuses no springs for the locking pins at all, and thatthis locking means could be applied to a single bolt as well as to a Ushaped element as shown for the sake of illustrating the principle ofits operation.

Having thus described and illustrated the preferred embodiment of myinvention, I do not wish to limit myself to the exact construction orarrangement of parts shown, since it is self evident ,that modicationsmay be made therein, without departing from the spirit of the inventiono scope of the claims. l

I claim: l. In a lock, the combination of a body, a centrally arrangedfixedv cylinder in said body, a

plurality of transverse holes in said cylinder, a

plurality of locking pins in said holes, a liat keyway on one side ofsaid holes, a plurality of slots connecting said keyway with the saidholes, pins in said locking pins passing through the said slots into thesaid keyway, and means adapted to cause said locking pins to projectinto and out of the path of a movable body.

2. In a lock, the combination of a body, a centrally arranged fixedcylinder in said body, a flat keyway one side of the centerline and insaid cylinder, a plurality of transverse. holes adjacentsaid keyway, aplurality of locking pins in said holes, a plurality of slotscommunicating with the said holes and the said keyway, a plurality ofpins in said locking pins passing through said slots into said keyway,and a key adapted to arrange said locking pins into and out of the pathof a movable body.

3. In a lock, the combination of a body, said body centrally holdingacylinder, an opening adrality of slidable locking pins in said holes, ajacent the periphery of said cylinder slidably plurality of pins in saidlocking pins, projecting carrying a movable body, a keyway adjacent saidinto the said keyway, and a key adapted to move periphery in saidcylinder, a plurality of transsaid locking pins into and out of the pathof verse holes below and adjacent'l said keyway, slots 5 a movable body.

connecting said holes with said keyway, a plu- EMIMA ENOS.
